Claims.

My invention relates to typewriting or like machines and moreparticularly to card feed mech anism therefor.

The main object of my invention, generally 5 stated, is to providecomparatively simple yet highly effective mechanism of the characterspecied, capable of rapid use with cards that vary in size and characterbut particularly adapted for handling cards provided with projections ortabs within the outline thereof by which the cards may be connected onewith another in given relation. In the employment of the devices of myinvention in connection with such cards the tabs are protected andcannot be torn or mutilated by fouling on parts of the machine duringthe feeding of the cards.

A further object of my invention is to provide mechanism of thecharacter specified that may be readily introduced as attachments toexisting typewriting or like machines withoutmodifying, or materiallymodifying, the existing structural features thereof.

A still further object of my invention is to provide a card clampcooperative with and adapted to protect the tabs on cards of thecharacter specified and to provide means whereby said clamp may bereadily detached Vfrom the platen to condition it for ordinary use whendesired.

To the above and other ends which will hereinafter appear my inventionconsists in the features of construction, arrangements of parts andcombinations of devices set forth in theY following description andparticularly pointed out in the appended claims.

I have shown my invention embodied in the present instance in a No. 6Remington Noiseless typewriting machine in which the devices of myinvention may be readily incorporated without modifying, or materiallymodifying the existing structural features of said machine. It should beunderstood, however, that my invention is applicable to typewriting orlike machines generally and may be incorporated in many different makesof such machines with more or less facility.

The carriage of machine in theV present instance comprises a supportingcross bar 1 grooved on opposite faces at 2 to form race-ways to receiveanti-friction rollers 3 on which the carriage is supported for movementfrom side to side of the machine in its step by step letter spacemovement. The supporting rollers 3 are likewise Vreceived in oppositelydisposed grooved faces or race-ways 4 of a carriage supporting member 59-0 which constitutes part of the case shift frame. The carriage furthercomprises end plates 6 secured to the cross bar 1 near the ends thereofand in bearings in which end plates a cylindrical platen 7 is supportedto rotate. The right-hand end of the platen is provided with a spindle 8that is received in a bearing bushing 9 seated in an opening in theright-hand end plate 6 and provided with a headed portion 10. The outerend portion of this spindle 8 is threaded to coact with an interiorlythreaded hub 11 xed to the righthand finger wheel l2 for the platen.When the hub ll is screwed into position on the spindle 8 with the innerend of the hub bearing against the head 10 of the bushing 9, a screw 13is threaded into the interiorly threaded portion of the hub il and bearsat its inner end against the spindle 8 thus locking the hub and ngerwheel xedly to the spindle 8 to rotate therewith.

This is the usual form of construction employed 110 in the No. 6Remington Noiseless typewriting machine and is availed of in the presentinstance for mounting devices of my invention thereon.

Surrounding the hub 11 is a hub 14 oi a locking wheel 15 provided withteeth 16 with interdental, angular locking recesses 17. A spacing sleeve18 surrounds the hub 14 of the locking wheel 15 and is secured to saidhub 14 by a set screw 19. A crank arm 20 has its hub-like bearing endpierced to provide a bearing seated on the hub 14 so as to turn freelythereon around the axis of the platen. This crank arm is held inposition between the inner end of the spacing sleeve 18 and the wheel15. A finger piece or handle 21 is provided on the crank arm by which itmay be manipulated by the operator to turn the platen a limited extentbetween two relatively adjustable stops which limit the motion of thecrank arm and platen, as will hereinafter more clearly appear.

The limiting stops just referred to are formed as parts of two plates 22and 23 respectively shown detached in Figs. 10` and 11. A projectingnger 24 on the plate 22 constitutes one of said stops for limiting themotion of the crank arm in one direction, whereas a face or abutment 25on the other plate 23 constitutes a stop for limiting the motion of thecrank arm in the opposite direction. The plate 22 is pierced at 26 toprovide a bearing for the plate 22on the head 10 of the bushing 9. Theplate 23 is pierced at 27 to provide a bearing opening to receive theinner end portion of the hub 11 of the finger wheel 12. It will be seen,therefore, that each 'of these plates is adjustable to a limited extentaround the axis of the platen.

In order to uphold each of the plates in its adjusted position there isprovided an arc-shaped slot 28 in the plate 22. Said slot receives thestem of a headed screw 29 that is received at its threaded end in atapped opening in the end plate 6 of the carriage. A washer 30 isinterposed between the head of this screw and the face of the plate 22,thus holding the plate rmiy in its adjusted position when the screw 29is tightened, but affording a limited extent of adjustment of the plate22 when the screw 29 isA backed up. In a like manner the stem of a screw31 passes through a slot 32 in the plate 23, the stem of said screwbeing received in a tapped opening 33 in the plate 22. The plates 22 and23 are mounted in position between the wheel 15 and the adjacent endplate 6 of the carriage,

From anv inspection of Figs. 1 and 2 it will be seen that a slot 34extends longitudinally of the crank arm 20 and receives the unthreaded,shouldered portion of two headed screws 35 and` 36. The two screws attheir threaded end portions are received in tapped openings in a lockingmember or slide 37 and are fixed thereto to move longitudinally of thecrank arm 20 in the slot 34. The screw 36 is extended inwardly beyondthe locking member 37 to provide a stop pin 36a adapted to co'act withthe stops 24 and 25 on the plates 22 and 23 respectively to limit thethrow of the crank arm 20 in opposite directions. The inner end of theslide or locking member 37 is provided with a tooth 38 adapted to engagein any of the interdental spaces 17 in the locking wheel l5 and thuseect a locking connection between the crank arm 20 and the locking wheelwhich is secured to and rotates with the platen. When, however, theslide 37 is moved upward along the crank arm 20 to the releasingposition, as shown in Fig. 7.

A the tooth 38 is drawn out of engagement with the locking wheel, sothat at this time the platen is free to rotate independently of thecrank arm.

In order that the crank arm may be retained in normal position when itis disengaged from the locking wheel, I have provided a spring detentfor engaging the crank arm or the locking member 37 as clearly shown inFig. 7. From a consideration of this iigure it will be seen that thestop-like end 36a of the screw 36 is adapted to coact with an inclinededge or face 39 on the plate 23 as the crank arm is shifted to normalposition with the locking member 37 in its released position where itbears against a stop face or edge 40 on the plate 23. In this positionof the parts the pin 36=1 is received in a slight depression 41 in theplate 23. By forming a cutout 42-43 in the plate 23 there is sufficientresilience provided at that portion of the plate which is engaged by thepin 362t in the Fig. 7 position to provide a spring detent which tendsto hold the crank arm against accidental displacement from the Fig. 7position, as well as to maintain the locking member 37 disengaged fromthe locking wheel. This detent is intended for use when the card feedingdevices are to be thrown out of operation and the machine is to be usedfor ordinary work. Preferably, the depth of the recess 41 is sufficientto hold the crank arm 20 against accidental displacement without,however, causing said arm to exert a braking action against the platen.In order to provide for maintaining the locking member 37 againstaccidental displacement either from or to its locked position, I providea spring friction detent 44 which is in the nature of a leaf springbifurcated at each end to straddle the stem of the adjacent screw 35 or36 and to bear outwardly at the ends against the heads of said screwswhereas the intermediate, centrally disposed portion of the leaf springbears against the body portion of the crank arm with suiiicient frictionto maintain the locking member 37 in either position to which it may beshifted longitudinally of the crank arm 20.

With the aid of the crank arm, the platen may be shifted forward andbackward a predetermined extent depending on the relative adjustmentbetween the plates 22 and 23 and the stops carried thereby with whichthe stop pin 36a coacts. The object in turning the platen forward andbackward in the manner hereinbefore set forth is to position the platento receive a card in a denite predetermined relation to the platen andthen return the platen backward to bring the card secured in position onthe platen to a definite position with reference to the printing line,so that printing in a predetermined deiined position on the card,usually a single line near the top thereof, may be accurately effected.The printed card may then be withdrawn and the platen rotated forward ina position to receive a new card accurately located with the aid of thecard clamp as will hereinafter more clearly appear, and so on indenitelyalternatively moving the platen backward and forward a predetermineddistance depending on the depth of the card employed and the exactposition to which the card is to be brought with reference to theprinting line.

A card clamp forming an important factor of the present invention willnow be described.

This card clamp is preferably detachably engaged with the platen so thaton the removal of the `clamp and the release of the locking member 37the machine may be employed for ordinary uses. Referring moreparticularly to Fig. 8 wherein the card clamp is shown detached it willbe seen that it comprises a securing strip or member curved in crosssection to conform to the surface of the platen against which it is rmlyheld. Secured to and overlapping the securing strip is a relatively thinshielding strip 46 curved in cross section concentric with the surfaceof the platen. This shielding strip extends upwardly from the securingstrip when the latter is secured in place and overlaps the major portionof the card, indicated at C in Fig. 8, leaving only a comparativelysmall depth at the upper edge of the card exposed to receive one or morelines of typewriting, one line usually suhicing. This exposed edge ofthe card is indicated at 4'7.

Contained within the outline of the card are tabs 48 formed by cuttingthe body portion of the card through on the line 49. These tabsconstitute means whereby different cards are connected together in suchrelation that the upper edge of one card will extend above the upperedge of another adjacent card connected therewith, to display thewritten lines near the upper edges of the cards. It is importa-nt toreceive the cards within the card guide in such a manner that theprotecting shield 46 of the clamp will overlap the tabs and prevent themfrom being projected away from the face of the platen in positions wherethey would be apt to be torn or mutilated by fouling on parts of themachine when the platen is rotated.

By constructing the securing strip 45 and shielding member 46 in themanner indicated, and making the securing strip of relatively thickstock, I am enabled to provide an arresting edge or abutment 50 (seeFig. 9) at the upper edge of the securing strip. This constitutes a stopagainst which the bottom edge of the card C may be seated and the cardsquared, as indicated in Figs. 8 and 9. I thereby provide for securingthe card to the platen always in a xed definite relation.

I prefer also to employ a struck up ear 51 (see Fig. 8) at one end o-fthe protecting shield 46. This ear constitutes a side stop against whicha side edge of the card C may be caused to abut so as to maintain alwaysa definite relation between a card and the platen, considered lengthwiseof the latter. It will be understood the shielding member 46 is slightlyresilient and is effective to maintain a card against the surface of theplaten in a curved condition, as shown in Figures 1 and 3.

Any suitable means may be employed for detachably connecting the cardclamp to the platen. However, I prefer to employ some such means asthose about to be disclosed inasmuch as it is unnecessary, with the aidof such means, to mutilate the face of the platen in order to providefor detachably connecting the card clamp thereto, so that in the eventthat the machine is to be used for `ordinary purposes the face of theplaten remains intact. Moreover, the -present construction fordetachably connecting the card clamp to the platen enables me to employstandard platens and apply the devices of my invention thereto withoutmodifying the existing structural features of the platen.

At one end of the platen I secure a bracket plate 52 with the aid ofscrews 53 which are received in tapped openings in one of the platenheads. This bracket plate is provided with a slot A54 bounded on oneside by the body of the plate 52 and on the other side by a cross bar 55which forms part of the plate. From an inspection of Figs, 6 and 8 itwill be seen that there is provided at each end of the securing strip aninwardly bent arm 56 that terminates in a locking lug or projection 57.The parts 56-57 thus constitute a hook-like engaging member that isadapted to be received in the slot 54 in the bracket plate and engagebehind the cross bar 55 thereof. Engaged in this manner the securingstrip 45 is detachably connected to the platen at one end. The oppositeend of the securing strip is also provided with a corresponding engagingmember, designated by the same reference numerals 56-57, and is adaptedto engage in a like manner a bracket plate 58 secured to the oppositeend of the platen by screws 59. In this instance, however, the bracketplate is in the nature of a spring plate secured at one end and free atthe other end to be flexed outwardly away from the end of the platenunder the inherent force of the spring of the plate, and thus maintainthe cross bar 60 thereon interlocked with the associated hook--likemember 56-57 on the securing bar. An inward pressure on the free endportion of the plate 58 is effective to release the cross bar 60 thereoffrom engagement with its cooperating hook-like member 56-57 on the cardclamp, thus releasing the clamp from the platen and enabling it to bedetached therefrom.

The stem of a headed screw 6l passes freely through an opening in thespring plate 58 and is received at its inner threaded end in'a tappedopening in the adjacent platen head. The head of this screw coacts withthe spring plate 53 to limit the outward movement thereof when it isreleased from interlocking engagement with the card clamp. The cardclamp being detachably connected to the platen in the manner indicated,and assuming the parts to be in the Fig. 3 position, is ready to receivethe lower major portion of a card behind the shield 46, the lower edgeof the card at this time abutting the upper edge 50 of the securingstrip and abutting the end stop 51 on the shield 46 in order :toaccurately position the card relatively to the platen. The crank arm maythen be drawn forward effecting a backward rotation of the platen to theFig. 1 position, where it is arrested by the cooperation of the stops 24and 36a.. At this time the card is positioned to receive a line ofwriting along the top edge thereof as indicated in Fig. l where thedotted line a indicates the r printing line.

During the backward rotation of the platen just described, theunprotected upper edge portion of the card will be brought intocooperation with the usual spring pressed line gage 62 and is reversedcarrying it back to the 3 position, where it is arrested by thecooperation of the sto-ps 36a and 25 and where the card may be removedand a new one inserted.

From the foregoing description it will be seen that I have providedcomparatively simple and highly effective means for rapidly feeding thecards accurately to position in the machine, for writing near the upperedges thereof and for protecting cards of the character described frommutilation during the feeding ofthe card with the platen.

It will also be understood that the devices of my invention may bereadily applied to existing machines without modifying, or materiallymodifying, the existing structural features thereof.

Various changes may be made inthe construction without departing from myinvention as it is defined in the accompanying claims.
